Hi Benjamin,
if I understand correctly the problem is a intensive work on the DB, that, added to the slow connection, make WOMonitor return the "No Instance Available" error.
 
if used in local network, these pages use more than 3/4 seconds to load? I'm asking this, because I think it's a good practice in these scenarios to introduce an intermediate page with a ERXLongResponseTask.DefaultImplementation subclass and a ERXLongResponsePage component to let the user see a loading page while fetching from the DB (example Search Result in large DB), before render the component.

Is it possible to you to alterate the WO App to do this?

Another solution can be to optimize the DB (maybe moving on a dedicate machine, physical or virtual, configured to speedup db results), making the fetch result in few seconds.

Bye

Hi Everyone,

I’m wondering if any of you kind souls can help me. :)

I’m in Singapore working off a VPN connection to the States, and while waiting for some database-intensive components to display, I keep getting “No Instance Available” because it’s taking so long to complete all the queries (ping times ~ 200ms).

I’ve tried going to WOMonitor on my local machine (localhost:56789) and modified the Send, Receive and Connect timeouts, but that didn’t seem to help. I’ve also tried changing WOMaxSocketIdleTime and WOLifebeatInterval in my Eclipse debugging profile, but that didn’t help either.

Does anyone have any ideas?

Thanks,
Ben
